Broken-symmetry phenomena enhanced by quasi-bound states in the continuum
Jan David Fischbach, Lukas Rebholz, Nikita Ustimenko +3
Many of the most powerful and elegant models in physics are grounded in symmetries. In electrodynamics, for example, geometric symmetries govern the observable effects of light-mat…

Photonic time crystals assisted by quasi-bound states in the continuum
P. Garg, E. Almpanis, L. Zimmer +8
Photonic time crystals are a class of artificial materials that have only recently been explored. They are characterized by the ultrafast modulation of the material properties in t…

Studying thermal radiation with T-matrices
Juan Diego Mazo-Vásquez, Markus Nyman, Marjan Krstić +3
We introduce a basic formalism for computing thermal radiation by combining Waterman's T-matrix method with an algebraic approach to light-matter interactions. The formalism applie…
